How to factory reset / clear pairing history of Pebble?

To factory reset/clear the pairing history on the Pebble, you need to reset the Left and Right earbuds separately.

First, take the Left earbud out of the case and wait for a few seconds until it flashes RED and BLUE, indicating that it is in pairing mode. Then, double-click the Multifunction Button (MFB). The LED will turn solid PINK for 2 seconds, then go off.

Next, do the same procedure on the Right earbud.

Finally, put both the Left and Right earbuds in the case, then take both of them out at the same time. Both LEDs on the earbuds will start flashing BLUE, indicating that they are connecting to each other (normally this process is very quick). When the Left and Right earbuds are connected, either earbud will go into pairing mode automatically, and you can pair them with your devices.
